    • A process and apparatus are disclosed for the deposition of a layer of a first material onto a substrate of a second material. Powder particles of the first material are entrained into a carrier gas flow to form a powder beam directed to impinge on the substrate. This defines a powder beam footprint region at the substrate. The powder beam and the substrate are moved relative to each other to move the powder beam footprint relative to the substrate, thereby to deposit the layer of the first material. A laser is operated to cause direct, local heating of at least one of a forward substrate region and a powder beam footprint region. The laser is controlled to provide a spatial temperature distribution at the powder footprint region of the substrate in which the local temperature of the substrate is in the range 0.5Ts to less than Ts in a volume from the surface of the substrate at least up to a depth of 0.2 mm from the surface of the substrate and not more than 0.25Ts at a depth of 1 mm from the surface of the substrate, wherein Ts is the solidus temperature (in K) of the second material.
    • 公开了一种用于将第一材料层沉积到第二材料的基底上的方法和装置。 第一材料的粉末颗粒被夹带到载气流中以形成指向冲击在基底上的粉末束。 这定义了衬底处的粉末束覆盖区域。 粉末束和基底相对于彼此移动以相对于基底移动粉末束覆盖,从而沉积第一材料的层。 操作激光器以对正向衬底区域和粉末束覆盖区域中的至少一个进行直接的局部加热。 关于在从平面到激光束方向的仰角和激光束覆盖区的中心处的基板的表面与激光束覆盖区的中心一致或相切的平面的激光束方向被限定,并且就锐角方位 从运动方向到激光束方向的角度。 仰角为80°以下,方位角为±60°以下。 在该装置中,提供了围绕粉末束足迹排列的至少三个激光源,激光源之间的角度间隔为120°或更小。
